$ !	This DCL command procedure executes the vimtutor command
$ !	(suprise, suprise!) which gives you a brief tutorial on the VIM
$ !	editor. Languages other than the default are supported in the
$ !	usual way, as are at least some of the command qualifiers,
$ !	though you'll need to play some fairly serious games with DCL
$ !	to specify ones that need quoting.
